摘　　要：用单车道元胞自动机交通流模型研究了随机减速概率对车间距的统计分布情况。计算机模拟结果表明:当车子密度处于高密度时,随机减速概率对车间距分布几乎没有影响;当车子密度处等于临界密度时和低密度区域内,随机减速概率对车间距统计分布有很重要的影响。Based upon the single--lane traffic Cellular automaton （CA） model, this paper studies the relation of vehicle gap distribution with the random deceleration probability under given vehicle density. Computer numerical simulations have been carried out, The results show the random deceleration probability have no effect on vehicle gap distribution under high vehicle density; but when vehicle density equal to critical, and low values, the. random deceleration probability have great effect on vehicle gap distribution.
